This is my second project. When I built my first robot I was not aware of this site, so I'll post about that in few days. This robot is a minor modification for the first. In first I was using SRF05 as an Input sensor. In this version I replaced it with APC220 Module. Now I can leave the robot untouched and I can experiment on the remote control side. On the remote I can use Accelerometer, Wii nunchuck, Processing, USB Mouse and tons of more input devices which I've not even thought ...
